derived from the phrase "spitting image double"….taken from the 80’s/90’s tv series…..by rights it should really be “spit dubs” but the 'U' was dropped in favour of the 'A' at some point, it may well have been of "saarf Landan" decent.

"Here Geeza, you seen that bird over at the bar? She looks the Spit Dabs of that tasty bit off the television".
